Background Noise


lisakgolf

Question

I interviewed a subject and neglected to use an external microphone. As a result, I picked up all kinds of background noise.

 

I have tried to eliminate it using the advanced audio equalizer, but that doesn't seem to work.

 

I've tried both EMC 7.5 and 8.0 - no luck. In fact when I run the video in 8.0 the audio and video are out of sync.

 

Any thoughts?

 

Thanks!

What you are trying to do is almost impossible without really specialized software. :) Think of removing specific colored balls (sound frequencies) from a bin of balls that are nearly the same color (sound frequencies). Actually it is much more difficult than that because you have to remove certain colored balls from a bin that contains all of the colors (sound has a bunch of different)

You might try using Audicity or GoldWave to try to remove specific frequencies. GoldWave has a liberal free trial. It gives you a more options and adjustments than Sound Editor.

 

You will have to extract the audio from the video you produced. Process it and than put it back into your production. When you do that, you will have to minimize the volume of the clips native track.

 

If your production is pretty long and you have a older computer, there is a possibility of haveing a video sync problem. There are several methods that you can use to eliminate sysnc problems. Also, you may want to break the long interview down into shorter seqments, fix each of the sound sections separately but equally and then put them back into the production with perhaps a fade to hide your video breaks.

Thanks so much for the excellent explanation and for educating me! I think I will chaulk this video up to a learning experience.

 

Thanks again.
